FIELD OF THE INVENTION

This invention relates to daily necessities for furniture, especially anedge-sealed table top panel with paper honeycomb cores.

DESCRIPTION OF THE PRIOR ART

Tables are one of the necessities using for family and offices, andthere are a great variety of tables with broad applications, such astables for work and study, council boards for various meetings, smallfamily dining tables, big dining tables for hotel and restaurant,leisure tables for recreation and entertainment, as well as computertables. The table is generally made up of a top panel and supportingtable legs. A key part of a table, the top panel is used for writing,handling official business, having dinner and placing articles.Currently, most of the top panels of indoor and outdoor products such asoffice table, dining table, council board, leisure table and computertable are made of wood, fiber board or particle board, and some blowmoulding plastic plate. The raw material of aforementioned table toppanels is mostly wood, which will be greatly limited by restrictions totree cutting as forest resource is decreasing. On the other hand, thereare some drawbacks for the table top panel made of woody materials. Forexample, it is too heavy to move a fiber board of medium density and toovulnerable to maintain a particle board as it is week in strength.What's more, it is hard to clean such top panel due to its poor moistureresistance. Meanwhile, the cost of table top panel made of woodymaterials is higher as a result of expensive raw material. Although thetable top panel made of one-piece blow moulding plastic plate is lightin weight, it is expensive in manufacturing and difficult in changingshape.

The existing paper honeycomb core panels are mainly used in the packageof fragile articles or stack board for transportation, and the furnituremade of them is poor in appearance; besides, the present honeycombcardboard can not be nailed, drilled or connected with other parts tobecome furniture or products. But as the large honeycomb paper providesadequate compressive strength and light weight, it is an appropriateenvironmentally friendly product with broad perspectives in furnitureand office furniture.

SUMMARY OF THE INVENTION

This invention is intended to overcome the technical roadblocks andprovide a lightweight edge-sealed table top panel with paper honeycombcores, which is environmentally friendly, beautiful, highly strong,cost-effective, and easy to clean.

According to the present invention, there is provided a technicalsolution to said roadblocks: An edge-sealed table top panel with paperhoneycomb cores comprising a top panel, a bottom panel, paper honeycombcores and an internal fixed part, in which the paper honeycomb cores arefilled in the closed space which is enclosed by the top panel and thebottom panel, and are fixed with the top panel and the bottom panel byglue; the peripheries of the paper honeycomb cores are completely orpartially surrounded by the internal fixed part, which can be positionedagainst the paper honeycomb cores; the edge of top panel bends andextends downwardly, covering the side edge of internal fixed part orupper edge of the bottom panel, and the lower edge of top panel isjointed with the upper edge of the bottom panel.

The internal fixed part is mainly used for connection and reinforcementand can either form a close inner frame in shapes of rectangle, roundand ellipse, or a frame like U-shape frame or two parallel bars alonglong edges of the top panel. Of course, instead of forming an innerframe, it can only be set in positions necessary for reinforcement orconnection. For example, it can be set fully or partially along theinner side of outer edge of panel. The internal fixed part can be pipefittings, section bars or plates. The paper honeycomb is allowed to becompressed in small area; therefore, if the plate internal fixed part isset partially, it can be overlapped on the paper honeycomb coresdirectly and need not to make room by honeycomb paper core. If the pipefittings or section bars are used as internal fixed part, normally thepaper honeycomb cores shall make room for them in the set position, ormake a concave cavity in the bottom panel to place the internal fixedpart. The position of internal fixed part and paper honeycomb cores canbe set upon request by fixing the top panel and bottom panel with thepaper honeycomb cores.

The said internal fixed part is pipe fitting or extrusion section bar orinjection-molded fittings or composite work piece constituted byhardware and it can be used to enhance the connection strength ofreinforced table leg mechanism and table top panel.

The top panel and bottom panel are made by suction moulding process orcontour machining process; and the former technique features not only insimple equipment but also in that decorative process such as grainpasting may be undertaken to the top panel.

One of the connection methods of top panel and bottom panel in thisinvention is that the edge of bottom panel bends upwardly and partiallycovers the internal fixed part, and the edge of top panel bendsdownwardly and covers the side edge of internal fixed part and edge ofbottom panel, with the side edge of top panel fixed to bottom panel atthe side edge of internal fixed part.

One of the connection methods of top panel and bottom panel in thisinvention is that the edge of bottom panel lays against the bottom lineof the internal fixed part and is fixed to the center of the bottom lineof internal fixed part, while the edge of top panel bends downwardly andcovers the side edge of internal fixed part and is fixed to the edge ofbottom panel at the bottom line of internal fixed part.

One of the connection methods of top panel and bottom panel in thisinvention is that the edge of starting end of upwardly bending bottompanel protrudes the top panel at a thickness of top panel and extendsupwardly; meanwhile, the side of downwardly bending top panel is bondedto the upwardly extension section of bottom panel and forms a plane withthe protruding section. This structure can be in invert order, i.e. thetop panel protrudes the bottom panel at an approximate thickness of sideedge of bottom panel.

The said paper honeycomb cores can be of one-piece located in the centerof internal fixed part, or several pieces inside or outside of internalfixed part.

The said paper honeycomb cores are made of monolayer paper honeycombcore. The said paper honeycomb cores are made of monolayer honeycombcardboard which is composed of paper honeycomb cores, top sheet andbottom sheet, wherein the paper honeycomb core is held between andbonded to the top sheet and bottom sheet.

The said paper honeycomb core is made by two-layer or multilayerhoneycomb cardboard, all layers of which are fixed together, and theshape and size of honeycomb cardboard in each layer can be different.The honeycomb cardboard is composed of paper honeycomb core, top sheetand bottom sheet, wherein the paper honeycomb core is held between andbonded to the top sheet and bottom sheet.

The shape of said top panel and bottom panel is square or rectangle orround or ellipse or triangle or polygon or profiled, or can be designedby requirement for table.

The said bottom panel can also be of one-piece with several reinforcingribs to reinforce the strength of table top panel.

According to the present invention, there is provided another technicalsolution to said roadblocks: An edge-sealed table top panel with paperhoneycomb cores comprising a top panel, a bottom panel, paper honeycombcores and an internal fixed part, in which the paper honeycomb cores arefilled in the closed space which is enclosed by the top panel and thebottom panel, and are fixed with the top panel and the bottom panel byglue; the internal fixed part is installed at the connection position oftable top panel and table leg or other parts, and can be positionedagainst paper honeycomb cores; with the edge of top panel bends andextents downwardly and the upper edge of the bottom panel bends andextends upwardly, the lower edge of top panel is bonded and fixed toupper edge of the bottom panel.

The internal fixed part is also mainly used for connecting andreinforcing and can either form a close inner frame in shapes ofrectangle, round and ellipse, or a frame like U-shape frame or twoparallel bars along long edges of the top panel. Of course, instead offorming an inner frame, it can only be set in positions necessary forreinforcement or connection. It can be set fully or partially along theshape of outer side of the panel. The internal fixed part can be pipefittings, section bars or plates. The paper honeycomb is allowed to becompressed in small area; therefore, if the plate internal fixed part isset partially, it can be overlapped on the paper honeycomb coresdirectly and need not to make room by honeycomb paper core. If the pipefittings or section bars are used as internal fixed part, normally thepaper honeycomb cores shall make room for them in the set position. Theposition of internal fixed part and paper honeycomb cores can be setupon request by bonding the top panel and bottom panel with the paperhoneycomb cores.

Another technical method to achieve purpose of this invention is toconvert the above mentioned internal fixed part to an outside frame, andembed the paper honeycomb core plate into the frame, thus forming atable panel with the outside frame and core plate; the paper honeycombcores may either contain none or one internal fixed part to enhance thepartial strength. It means that the table top panel is composed ofoutside frame and paper honeycomb core plate, with the paper honeycombcores filled between the top panel and bottom panel to form a paperhoneycomb core plate which is then embedded into the outside frame toform the table top panel, and the table leg is connected to the outsideframe of table top panel.

In addition, the bar of the said outside frame has an inward concavestep, into which the paper honeycomb core plate is embedded, with thehoneycomb cardboard embedded into the outside frame.

In manufacturing, the top panel and bottom panel may be made ofmonolayer plastic plate or multilayer plastic plate and processeddirectly to desired shape and size of table top panel; when adopting themonolayer plastic plate, the plate thickness may be around 0.3 mm-4 mmand the material can be ABS, PP, PS, PE, etc.; when adopting themultilayer plastic plate, the thickness of plastic plate can be about0.3 mm-4 mm, for example, the plastic plate can be composite sheetcompounded by 0.1 mm-0.3 mm ASA and 0.3 mm-3.5 mm ABS. The paperhoneycomb cores can be monolayer paper honeycomb core or monolayerhoneycomb cardboard or two-layer honeycomb cardboard, or multilayerhoneycomb cardboard; when adopting two-layer or multilayer honeycombcardboard, the size and shape of each layer of honeycomb cardboard caneither be identical or variant. Put the paper honeycomb cores betweenthe plastic top panel and plastic bottom panel, and fix it to plastictop panel and plastic bottom panel respectively with glue. Thesurroundings of the paper honeycomb cores are completely covered byinternal fixed part, which forms an outside frame; said internal fixedpart can be pipe fittings or extrusion section bar and injection-moldedfittings or composite work piece constituted by hardware and it can beused to enhance the connection strength of reinforced table legmechanism and table top panel, therefore, the internal fixed part shallbe the reinforced frame of table top panel, and may only be used forconnecting rather than strengthening enhancing the connection strengthof table leg mechanism and table top panel. The internal fixed part canbe fixed together by glue with honeycomb paper cores or they can not beunnecessarily fixed; the edge of top panel and the edge of bottom panelor connection of bottom panel is fixed by glue and the edge of bottompanel and connection of internal fixed part is fixed by glue, forming acomplete table top panel whose edge is made by bending of top panel.

The beneficial effect of this invention is as follows. Firstly, as thelightweight paper honeycomb core is used as the filling between toppanel and bottom panel, i.e. the core of table top panel, the finishedtable top panel is light in weight. Secondly, the internal fixed partsuch as core set in the paper honeycomb cores is completely or partiallycovered with composite work piece made of pipe fittings or extrusionsection bars, or composite work piece constituted by pipe fitting orextrusion section and injection-molded fittings or hardware, enablingconnection between the table top panel and other parts like table legmechanism. Furthermore, it may be used as the reinforced frame of tabletop panel to greatly enhance the strength of table top panel. Thisinvention particularly adopts the above mentioned edge-sealed structurein top panel and bottom panel, which makes the paper honeycomb coreplate good-looking and is useful in improving the production efficiency.

Since the top panel and bottom panel are formed by monolayer plasticplate or multilayer plastic composite plate made by suction mouldingprocess or contour machining process, the table top panel can bedesigned in various shapes upon requirement without further processingand is easy to clean and strong in moisture resistance; the edge oftable top panel is formed by bending panel, ensuring a more smooth andbeautiful table top panel which is quite flat and seamless withoutbonding gap. An edge-sealed table top panel with environmentallyfriendly paper honeycomb cores which is made of invert suction mouldingprocess is characterized by light weight, high strength, easymaintenance, cost-effectiveness and beautiful appearance.
